Lpg Conversion On A R33 And No Dynometer

[samuri]

I have a non turbo 1996 skyline which has just beeen converted to LPG.

The Dyno was broken and couldnt be used so the car was tuned in the garage.

Will there be any or much difference if I go back and ask for a dyno tune when the dynometer is fixed up?

If it was a turbo would your response be any different?

I suspect the fuel econmy could be better but I am still getting used to the conversion.

The system is SVI (sequential vapour injection) and I am assuming an extra 20% fuel consumption compared to petrol.

What do you mean by it was tuned in the garage

To the OP you definetly have to get it dyno tuned under load otherwise its all just guess work by the tuner and a close enough approach that is most likely going to run rich eating fuel like crazy. Using guess work you gotta be on the safe side so they definetly cant have you coming back with your engine blown to pieces because they cbf fixing their dyno.

There would most likely be a world of difference in terms of both response and economy if it is taken back and tuned properly.

Out of curiousity what ECU are you using for the conversion?

A garage is where a mechanic usually works.

The conversion was an EMER system supplied by Aust warehouse LPG. Does thta help with the ECU type?Where would I look?

Thanks for that bit of knowledge, now I can finally complete my Masters Degree in Engineering. Cheers.
